Amazon's been under quite a bit of stress recently, as it deals with fallout from its facial recognition tech, ongoing privacy concerns with its Echo hardware and its Prime Day not going as well as intended. But with so many businesses under its umbrella, Amazon still raked in plenty of dough to keep the company going. According to its second quarterly report for 2018, Amazon's net sales increased by 39 percent to $52.9 billion compared to this time last year, which translates to an overall net income of $2.5 billion in just the past few months. This includes sales from advertising, its own hardware products, the Prime Video service, plus sales from Whole Foods stores across the nation. Amazon doesn't typically break out sales by category, but it does seem like the company has been pushing hard on the Alexa side of things in the past few months.
